Hanna Instruments BL981411 pH Mini Controller
The BL981411 is a small pH process controller created for applications where cost or available space are critical factors. Any pH electrode with a common BNC connector can be used with the instrument’s high impedance pH input.
Its programmable pH setpoint can be dosed above or below using the adjustable dosing relay. Users can select between automatic and manual dosing modes, making maintenance and troubleshooting simple.
Large Clear LCD
A large LCD clearly displays the parameter you are monitoring.
Fire Retardant Casing
Special materials provide additional protection in the event of an emergency.
BNC Connection
The controller’s high impedance pH input may be used with any pH electrode with a standard BNC connector.
Adjustable Dosing Relay
The dosing relay of the BL981411 can be set up to dose above or below a user-programmable pH setpoint.
Selectable Overdose Protection
If a valve, pump, or connected device is activated for longer than a certain period of time—which can be anywhere between 5 and 30 minutes—the small controller can be set to disable it.
Selectable Control Override
Your linked device may be turned “Off” from functioning or always “On” with the flick of a switch, overriding the device’s default “Auto” operation.
Fuse Protected Dosing Contacts
A connected pump or other equipment can draw up to a 2A load without damaging the tiny controller.
Easy Peripheral Connection
Power, communication, dosage control, and sensor connections can all be made quickly and easily using quick-connect terminal blocks.
Matching Pin Connection
A corresponding pin option included into the sensor helps shield it from ground loop effects that could cause erroneous readings or system harm.
Front View
Installation cut-out dimensions are provided as well as outside panel dimensions.
Side View
Adjustable location brackets allow the controller to slide easily and securely into place.
